Botanical designation rosa hybrida variety denomination &#39;Poulpar048&#39;

ABSTRACT

A new miniature rose plant that has abundant, red flowers and attractive foliage. The variety successfully propagates from softwood cuttings and is suitable for year-round production in commercial glasshouses. This new and distinct variety has shown to be uniform and stable in the resulting generations from asexual propagation.

BOTANICAL DESIGNATION

Rosa hybrida

VARIETY DENOMINATION

‘Poulpar048’

SUMMARY OF THE INVENTION

The present discovery constitutes a new and distinct variety ofminiature rose plant which was discovered in a cultivated area. The newrose variety resulted from a naturally occurring mutation of unknowncausation on a branch of ‘Poulpar029’, U.S. Plant Pat. No. 16,148. Theresulting mutation was selected and evaluations were conducted on theresulting rose plants in a controlled environment.

The rose plant of the present discovery has a unique combination ofcharacteristics which are outstanding in the new variety and whichdistinguish it from the original rose ‘Poulpar029’ as well as all othervarieties which we are aware of. ‘Poulpar048’ tends to branch better andhas larger flowers than ‘Poulpar029’.

The criteria used to evaluate the claimed plant were selected in orderto introduce a distinct variety for garden use with unique qualities,such as:

-   -   1. Uniform and abundant red flowers;    -   2. Vigorous, but compact growth when propagated on its own        roots;    -   3. Exceptional disease resistance; and    -   4. Durable foliage and long lasting flowers.

This combination of qualities is not present in previously availablecommercial cultivars of this type, known to the inventor, anddistinguish ‘Poulpar048’ from all other varieties of which we are aware.

Asexual reproduction of ‘Poulpar048’ by vegetative cuttings was firstdone by Mogens N. Olesen in Fredensborg, Denmark, in July of 2001. Thisinitial and other subsequent propagations have demonstrated that thecharacteristics of ‘Poulpar048’ are stable and reproduced true to typein successive generations of asexual reproduction.

BRIEF DESCRIPTION OF THE DRAWING

The accompanying color illustrations show as true as is reasonablypossible to obtain in color photographs of this type, the typicalcharacteristics of the buds, flowers, leaves, and stems of ‘Poulpar048’.

DETAILED DESCRIPTION OF THE VARIETY

The following is a description of ‘Poulpar048’, as observed in itsgrowth in a glasshouse in Fredensborg, Denmark. Observed plants are 3months of age and were cultivated in 10.5 cm pots. Color references aremade using The Royal Horticultural Society (London, England) ColourChart, 2001, except where common terms of color are used.

For a comparison, two physical characteristics of the rose variety‘Poulpar029’, U.S. Plant Pat. No. 16,148. are compared to ‘Poulpar048’in Chart 1.
